Rancho RS7MT 2.5-4″ Rear Lift Shocks for 1969-1991 GMC Jimmy 4WD

Part Number: RS77112

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on vehicles with 2.5 to 4 inches of rear lift. Utilizing a sophisticated monotube design, these shocks provide the precise damping needed to eliminate aeration during aggressive off-road maneuvers. Whether navigating technical trails or maintaining stability on the highway, the RS7MT provides a significant upgrade in response and control for your 4WD system.

Features

• Monotube Construction: A high-pressure nitrogen gas charge provides a quicker damping response to ensure consistent control on uneven terrain.
• Internal Floating Piston: The physical separation of gas and oil provides zero aeration to ensure fade-free performance during high-frequency cycling.
• Hardened Nitro-Chablis Piston Rod: A heavy-duty 14mm rod provides superior structural integrity to ensure long-term durability in harsh environments.
• OE-Style Mounts: Application-specific bushings provide a direct-fit installation to ensure reduced NVH (Noise, Vibration, and Harshness).

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks do not create lift; they are specifically valved and length-configured to work with a vehicle already equipped with a 2.5″ to 4″ lift kit.

What is the benefit of the Monotube design?
The monotube design allows for a larger piston and better heat dissipation compared to twin-tube shocks, preventing the oil from foaming (aeration) during heavy off-road use.

Are these sold as a pair?
Yes, this specific SKU (2xRS77112) includes a pair of two rear shocks.
